Application filed March 2, 1906l Serial No.'303;751.

To all. whomt may concern,.-

Beit known that I, KARL C. J. HANsEL- MANN, of the city of Baltimore andStatel of Maryland, have invented certain Improvements in Shutter-Fasteners, of which the following is a specification. f

In the further descri tion of the said invention which follows re erence is made to ther accompanying drawings, forming a part hereof, and in which- Figure l is a perspective view of' a part of the front of abuilding, together with parts of the window-sill, thewindow-frame, and one shutter, provided with the present invention. Fig. 2 is atop view of asemicircular adjustable .angentially-notched bar forming a part of the said invention. Fig. 3 is an edge view of the bar shown in Fig. 2. Figs. 4 and 5 are respectively a top and an edge view of a part of the notched bar on an enlarged scale. Figs. 6 and 7 are respectively a front and an edge view of a latch employed in connection with the saidy semicircular bar to hold the shutter in various positions with reference to at one end to the horizontal projecting part a of the window-frame) The other end of the ysaid bar is free or unattached to the building. In order that the semicircular bar 5 may be easily and readily fastened to the part a of the window-frame and admit of its adjustment in position without changing the situation of its attached end, or, in other Words,that the said bar may be thrown around or abouta centralpoint which must be at a certain distance from the center of the pintles of the hinges, whereby the shutter is connected to the window-frame, .the bar terminates in a circular disk c, adapted to 4rest 'in a .circular depression d in the part a of the window-sill, and to alloWof such adjustment the corners of the sill adjoining the said depression are cut away, as at e. only necessary in afixing the bar 5 to the window-frame to mark on the frame a point ,which has a distance from the hinge-pintle equal to the radius'of the `semicircular bar 3 is the window-frame, which is seated By this arrangement it is and then sink at that point a cavity in the frame having a diameter which is the same as that of the disk c.- The corners, as at e', are then cut away and the bar placed in position and held temporarily thereat by a central screw. The other end of the bar is then brought to the pro er distance from the center of the pintle, a ter which other screws are used to hold the bar in its now correct position.

The shutter, which is denoted by '7, is provided with a hole through which is inserted the free end of the semicircular bar before the `same is finally secured to the frame, and over this hole is fastened a latch 9, the bolt f of which bears on the upper surface of the bar 5. In order that the shutter may be held when fully open or closed or at certain'intermediate oints through the medium of the bolt, the ar 5 is rovided with notches g, adapted to receive t e end of the bolt f, and to provide for variations in the projectionvof, the hinge-pintles beyond the radial dotted line shown in Fig. 2, which would change the angle of the notches with respect to the radial line, the sides' of the notches are made curved, as shown in Fig. 4. v f

In the drawings the shutter is shown as in a half-open osition, and it will be understood that by li ting the bolt above the surface of the bar 5 the shutter may be-further opened or closed and held securely at Aany point at' which the bolt registers with a notch, and

when the shutter is' closed it cannot be yopened from the outside.

I claim as my invention.-

In combinationwith a window-frame havi ing a circular depression therein, and a shutter which is hinged yto the window-frame, a

fastener which consists of. a semicircular notched bar which'terminates at one end in a circular disk which vis placed inthe circular depression in the Window-frame, and a latch fastened to the shutter adapted to cooperate vwith the said notched bar to hold the shutter substantially as speciin various positions,

fied.
